== Advanced - Modify Code and Issues ==

==== Modify Transformer demo code ====
* The code main differences are the transformer.cc transformer.h
* notice to apply new transformer in your code, for example the demo code, ADD new line at 1163
matrix->ApplyStaticTransformer(rgb_matrix::EDTransformer()) ;
* compile again -> cd into folder and compile it: make -C example*
* now can start to run following demo

==== Apply new transformer ====
[[File:2018-07-16 183343.png|thumbnail]]
* Please refer to above 32*16 zip file code, you can search and file EDTransformer() in 3 files
* add as demo code to -> transformer.cc, before }; name_space rgb_matrix at the end
* add as demo code to -> transformer.h, before }; name_space rgb_matrix at the end
* add as demo code to -> led-matrix.cc, there are two lines
* apply transformer into demo in line 1162~1163 -> matrix->ApplyStaticTransformer(rgb_matrix::P10outdoorTransformer());

==== Transormer for 16x32x1/4 ====
* https://github.com/hzeller/rpi-rgb-led-matrix/issues/313
* https://github.com/hzeller/rpi-rgb-led-matrix/issues/242
* https://github.com/hzeller/rpi-rgb-led-matrix/issues/283
* Get P10 transformer from here: https://github.com/gausie/rpi-rgb-led-matrix/tree/p10transformer
* The file edited transformer.h and transformer.cc, and led-matrix.h

* RGBMatrix::RGBMatrix in led-matrix.cc, this is for python - > https://github.com/hzeller/rpi-rgb-led-matrix/issues/283
<syntaxhighlight lang="c">
int new_x = 0;
int new_y = 0;
if (y < 4 || (y > 7 && y < 12)) {
new_x = (x * -1) + (24 * ((x / 8) + 1)) - 17;
new_y = y;
} else {
new_x = x + (8 * ((x / 8) + 1));
new_y = y - 4;
}
delegatee_->SetPixel(new_x, new_y, red, green, blue);
</syntaxhighlight>

==== Transformer canvas part for 32x32x1/8 ====
* https://github.com/hzeller/rpi-rgb-led-matrix/issues/66
<syntaxhighlight lang="c">
new_x = ((x / 16) * 32) + (x % 16);
if ((y & 8) == 0) {
new_x += 16;
}
new_y = ((y / 16) * 16) + (y % 8);
</syntaxhighlight>
* Also in your transform class have:
<syntaxhighlight lang="c">
int myTransformer::TransformCanvas::width() const {
return delegatee_->width() / 2; }
int myTransformer::TransformCanvas::height() const {
return delegatee_->height() ; }
</syntaxhighlight>
* Change the define in framebuffer.cc to SUB_PANELS_ 4 and remake the librgbmatrix library.
* Try row = 32 and chains = double the number of panels in a chain.
===Apply transformer ===
* in demo-main.cc on line 1163 after the check for rotation:
matrix->ApplyStaticTransformer(rgb_matrix::Mikro2347Transformer());
sudo ./demo -D 0 --led-no-hardware-pulse --led-rows=16 --led-chain=2

=== Constant Matrix Drive ===
* [[File:TC5020-FUMAN.pdf|TC5020A constant current chipsets from Fuman electronics shenzen (24 pin)]]
